I have a 2020 C-HR and my glass never gets completely clean either! No other car I’ve ever owned has had that problem. The best way I’ve found is my own blend of water and a shot of vinegar wiped with a microfiber cloth, but even then it’s not great.It seems to me that the glass when I clean is not the same as the glass on older cars. The glass on
my 2018 does not seem to clean easily as the glass on my older cars and trucks. Anyone notice this also? Did
they change the substance of the glass?
